MOSCOW, November 20. /TASS/. A new regiment equipped with the S-400 Triumf air defense missile systems has taken up combat duty in the Moscow Region, a spokesman for the Russian Defense Ministry said on Thursday.

"The Russian Aerospace Defense Forces currently have four anti-aircraft regiments equipped with the newest S-400 Triumf systems that ensure air defense of Moscow and the central industrial region," Alexey Zolotukhin said.

S-400 Triumf (NATO Designation SA-21 Growler) anti-aircraft systems can engage targets at a maximum range of up to 400 km at an altitude of 40,000-50,000 meters.

The systems, which are capable of launching up to 72 missiles and engaging up to 36 targets simultaneously, entered service in 2007 to replace the S-300 systems.

Russia currently has a total of eight S-400 regiments deployed near Moscow, St. Petersburg, near the port city of Nakhodka in the far eastern Primorye Territory, in the Baltic exclave of Kaliningrad and in the Southern Military District.
